IMPROVEMENT IN HEATING AND VENTILATING APPARATUS FOR BUILDINGS.

Specification forming part of Letters Patent No. l$$,320, dated May 18,1875 application filed April 12, 1875.

To all whom it may concern Be it known that I, ORLANDO KELsEY, ofWorcester, Worcester county, State of Massachusetis, have inventedcertain new and usefulImprovements in Heating and Ventilating Apparatusfor Buildings; and I do hereby declare the following to be a full,clear, and pre cise description of the same, reference being had to theaccompanying drawings forming part of this specification, of which-Figure 1 is an elevation of the inside of a wall of a building, showingthe construction of my dues; and Fig. 2, a side view of theventilator-reflector.

Similar letters of reference indicate like parts in both the figures.

My invention relates to the thorough ventilation and purifying of theatmosphere of buildings. It consists, substantially, of a double ortwofold fluethe first to introduce the heat, fresh from the source ofsupply, into the room; the second, auxiliary to the first, to exhaustthe impure air, the two acting in conjunction to produce the desiredresult.

For the better information of the public, I will proceed to describe theconstruction of my invention in detail, and I speak now of Fig. 1. Arepresents the cellar of the building, 13 the first floor, and O and D,respectively, the second and third floors. E is a vertical heating-fluepassing up from the furnace L below to the third floor, where itterminates in a sheet-metal angular or spherical cap, 6, connecting withthe room D by a register, M. This cap is so constructed as to radiateheat very freely into the auxiliary ventilatingflue S adjoining. Thisauxiliary ventilatingflue S passes up from the first floor to the top ofthe house, and communicates with each floor by means ofventilatingregisters N I J alongside of the heat-registers.

These ventilating registers are provided with reflectors Z, as shown inFig.2, above the first story, to prevent the ingress of the foul aircarried up from the story below. Now, it will be readily understood,taking the third floor for illustration, that fresh heated air isadmitted into that floor by register M, the impurities in which air sinkto the bottom of the room, and are drawn into ventilator-register N byreason of the upward current of heated air generated in theventilating-flue S by the radiation of heat from the cap 0, and thenceascend and escape through the outlet K. The cap 6 is constructedconveniently with flanges for attachment of the registers, &c. Thisarrangement of lines, as will be seen, is carried out upon each floor,all ventilatingregisters opening into a common auxiliaryventilating-flue, S, or fines, where more than one are required. F is aheat-flue, supplying floor C, and covered by the cap f and register P,the arrangement being the same as on the third floor. Q is the cap and Othe heat-register on the first floor, and G the flue.

There is no connection between the heat and ventilating fines.

The'advantages of my device are its cheapness and the extreme purity ofthe atmosphere created by its employment.

Having thus fully described my invention, what I claim and desire to,secure is- 1. The auxiliary ventilating flue or lines S, adjoining theheat-flues E and F and G, and extending from first floor to top ofbuilding, and ventilating every story, in combination with theheat-fines E, F, and G, substantially as shown and described.

2. The caps e, f, and q, for forcing the ventilation, substantially asshown and described. 3. The reflectors Z, substantially as shown anddescribed.
